How are mitochondria similar to chloroplasts?
both have many layers of membranes.
both contain molecules of chlorophyll.
both are found in the cells of consumers.
both are needed for cells to store energy.

The most appropriate answer would be Both have many layers of membranes.  

Both mitochondria and chloroplasts are double membrane layered structure. They both have an outer membrane, inner membrane, and inter-membrane space.

Mitochondria are present in cells of all eukaryotic organisms including plants. They are also called the power-house the cell as their main function is to generate ATP (adenosine triphosphate), the energy currency of the cell.

The chloroplast is a chlorophyll-containing cell organelle usually present in green parts of the plants and in eukaryotic algae. Green plants are also called as autotrophs. They are mainly associated with photosynthesis that is, the synthesis of food with the help of sunlight.

Thus, we can say that both are similar in having two layers of membranes.

D. 1000 times smaller than those visible in light microscopes.
